[General] Galary2 and streaming video.

Thu Feb 14 13:26:17 +03 2008

So it seems there are three type of video viewing:
1. Download and then Play.
2. Buffer and Play
3. Play realtime  (RTSP)

When dealing with large video file and a relatively slow internet link, then ideally type 3 (RTSP) is required, but that need a client server cooperation , ie. The server have a streaming service and the UA is capable to decode and play on the fly.

The second option is type 2 (Buffer and Play) which does not require a server part, it looks that some UAs can download part of the file (buffer) and play the video as soon as the buffer is full. This is what is happening with flashvideo.
But could not confirm it with the MOV file type (Neither with Quicktime nor with VLC players)

Correct me if I am worng.

When you are talking about 'streaming', it means that a portion of the file is cached at the user agent, the rest is accessed on the fly as the file is being played.

To have the file simply play in the user agent, this is not streaming. 
This is embedding a player in the UA so that the UA does not get a 'save as' dialog box. The way to prevent this box is to register a handler in the UA for the mime-type. When you install quicktime, media player or VLC on your PC, it associates a control and registers itself as a handler for the mime type in the browser.  In this situation, in order for the file to be played, all of it must be stored in the UA cache.

Just to clear things up :)
